Floribunda rose plant named ‘Poulpal038’

ABSTRACT

A new garden rose plant of the Compact Floribunda class which has abundant, white flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulpal038 ’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between thefemale seed parent, an unnamed seedling, and the male pollen parent,also an unnamed seedling.

The two parents were crossed during the summer of 2004 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulpal038’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by flower coloration and growth habit.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant white flowers;    -   2. Vigorous, but compact growth when propagated both as a budded        rose and on its own roots; and    -   3. Exceptional disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulpal038’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2004 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulpal038’ was selected in thespring of 2005 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulpal038’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July, 2005. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulpal038’ are true to typeand are transmitted from one generation to the next.

Specifically illustrated in the drawing are flowers atvarious stages of development, flower in parts, leaves, and stems.Illustrated plants are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpal038’, as observed in itsgrowth in in a field nursery in Bakersfield, Calif. 2 years of age, andwere grown on their own roots. Color references are made using The RoyalHorticultural Society (London, England) Colour Chart, 2001, except wherecommon terms of color are used.

For a comparison, several physical characteristics of the rose variety‘Poulgret’, U.S. Plant Pat. No. 10,729 are compared to ‘Poulpal038’ inChart 1.
